Reddit reviews Low Shank 11 Piece Snap-on Foot kit

I got a kit on amazon that came with several feet (I bought it solely for the zipper foot I had lost, because it was cheaper than buying a zipper foot alone). It also came with an extension type piece that adds the piece to your machine where snap ons would attach, if your amchien doesnt have it. Some of the older machines dont have this piece, so it allows even those machines to use the universal feet. Janomes are typically not considered universal, though, from what i read but then again they all arent the same. Look at your machine and the attachable snap on adaptation piece...if itd fit, the feet will fit. If you already have the snap on piece built into your machine, just make sure its not too narrow and theyll fit. My kit was ~8$ with shipping and was labeled 11 piece kit, I believe. Edit: Here is what I bought.

Is your machine low shank or high shank?
I got mine on amazon as a set for my low-shank Kenmore. It comes with a buttonholer. It has an adapter so it should fit your singer as well.
